Chaos League is a 2004 fantasy-based sports management game developed by Cyanide Studios and published by Digital Jesters.

An official expansion was later released in 2005 bundled with the original, titled Chaos League: Sudden Death that added new features and gameplay tweaks.

Cyanide Studios would later develop the video game version of Blood Bowl in 2009, which itself utilizes certain features from Chaos League.
